Lee, Tsung-Dao (1926-)

Chinese physicist whose research centred on the physics of weak nuclear forces. In 1956 Lee proposed that weak nuclear forces between elementary particles might disobey certain key assumptions; for instance, the conservation of parity. He shared the 1957 Nobel Prize for Physics with his colleague Yang Chen Ning (1922- ).
Lee trained in China; a scholarship sent him to the USA in 1946, working mostly on particle physics at the Princeton Institute of Advanced Study and at the University of California.
